Abstract: A bushing for the manufacture of filaments, especially glass filaments including, on one of its faces a screen through which a molten material is intended to arrive via openings, and on its opposite face a bottom provided with plural orifices through which the molten material is intended to flow. A closure plate is attached and fastened to part of the total area of the screen.

Abstract: A scaffolding shelter having at least one wall and at least partially enclosing a scaffolding made of scaffolding sections. The scaffolding shelter comprises a plurality of self-supporting wall panels, each wall panel defining edges and being adapted to form at least a portion of a wall of the scaffolding shelter; and connectors adapted to provide engagement of the wall panels side by side, and one atop another; whereby the width and the height of the wall is adaptable by adjoining and superposing the wall panels side by side and one above another, respectively.

Abstract: The present invention relates to a transformable utility/ATV trailer (1) that can easily be adapted to mount to a large number of different types of vehicles and trailer hitches. Moreover, the trailer (3) can rapidly be converted from a short box/bed trailer (3) to a flat bed trailer (3). The tow structure (2) comprises a frame (4) for mounting to a trailer (3) or similar implement and a draw bar (5) having a first end with a first hitch coupler (6) and a second end with a second hitch coupler (12). The draw bar (5) is mounted pivotally to the frame (4) for movement between a first position in which the first end of the draw bar (5) extends forward of the frame (4), and a second position in which the second end of the draw bar (5) extends forward of the frame (4).

Abstract: A secured token comprises a token body and an antenna coupled to an integrated circuit. The outer surface of the token body has a non-recessed metallic region, such as an outer metal ring, which is disposed such that a metallic sound is generated when the secured token strikingly engages a metal object. The antenna and the integrated circuit are substantially disposed within the token body. The secured token advantageously makes a jingling sound similar to that of coins when a payout is made to a player, and has mechanical strength for protecting an electronic circuit placed in the secured token.

Abstract: The disclosure relates to games machines provided with electronic payment mechanisms. The conventional payment mechanism is replaced by a payment mechanism operating by means of tokens that are secured by contract-free detection and the machine is furthermore provided with a second payment mechanism operating by means of a chip card. Switching means make it possible to change over from the token-operated payment mechanism to the chip-card operated payment mechanism when a card such as this is inserted into the corresponding payment mechanism. This device makes it possible to increase the efficiency of the games machines.

Abstract: The invention relates to a terminal block for printed circuits boards, said terminal block including a base whose sides are intended to be assembled side by side with the sides of the base of an adjacent terminal block to constitute a single assembly therewith, a lower surface intended to be fixed on a common support, a front surface, a back surface and an upper surface which are intended to be connected to electric circuits, the terminal block is characterized in that the upper surface of the base (1) includes insulating supports (34) for a row of electric bus-bars (5) which are disposed parallel to the longitudinal axis of the assembly and are common to the set of blocks thereof, and contact (40) which are disposed facing said electric bars and are parallel thereto, said contact tabs being connected to terminals (4) for exterior connection disposed on the front and rear surfaces of the base, and in that a printed circuit board (7) is disposed transversally on said bars, the lower edge of the board having te

Abstract: A memory of the MOS N channel type comprising two half-memories each conting the same number of columns, each column being bisected at the center by a refreshing amplifier. A bus is alotted to each half-memory and is connectable to any half-column in the half-memory which is addressed so as to read and rewrite in the refreshing phase. The extracting and rewriting arrangement incorporates a flip-flop having its inputs connected to the buses by a differential circuit and its outputs connected to inputs of a read and rewrite circuit. The buses are initialized at a low potential and a reference potential is applied to one bus when the other bus is connected to a half-column. Transient interference rise on the selected bus above the disturbance threshold of the refreshing amplifier is prevented.

Abstract: A control signal generating circuit is provided which is capable of activating its output in one of two modes depending on whether a transition occurs between the levels of one of the two voltages before or after a similar transition between levels occurs in the other voltage.
